VCA-DCV is no longer available. You can directly start with VCP-DCV but if this your very first VMware Certification then training is mandatory. Refer this post you will get some idea Virtualization The Future: VMware Certification Tracks and Levels Explained
The only VCA now is in Digital Business Transformation (DBT).
What‘s your incentive for gaining a certification? If it’s to enhance your opportunity in working at a technical level with VMware products, look at the VCPs rather than the VCA.
Each VCP (there are 4) has certain requirements, although they change once you’ve gained your first one.
Yes scott28tt, the objective is to enhance my technical skills to be able to handle and be capable of managing/admin of an infrastructure. Thanks for the input guys, will look into the VCP
and thanks to RanjnaAggarwal for pointing out that VCA has been out and VCP is the new one.
